Two foliage plant species, Leea coccinia L. and Leea rubra L., exhibited lower light compensation points and faster rates of acclimatization than Ficus benjamina L. when moved from full sun to dense shade, i.e., from 15.7 to 0.26 or 0.09 mol·m·-2day-1. Light compensation points were reduced up to 75% for L. coccinia and 71% for L. rubra after 25 days under these conditions. Uptake of CO2 increased from 65% to 179% and 34% to 118% for L. coccinia and L. rubra, respectively, while respiration rates were reduced from 73% and 76% to 59% to 68%, respectively. Ficus benjamina plants died under similar conditions.
